Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
I haven’t got there yet sorry
Friend i'm guessing its the second answer
Just an educated guess
The answer is 7.
Step by step explanation:
Answer:
c = -4
Step-by-step explanation:
Step 1: Write equation
14 = -2c - 6 - 3c
Step 2: Solve for <em>c</em>
- Combine like terms: 14 = -5c - 6
- Add 6 on both sides: 20 = -5c
- Divide both sides by -5: c = -4
Step 3: Check
<em>Plug in c to verify it's a solution.</em>
14 = -2(-4) - 6 - 3(-4)
14 = 8 - 6 + 12
14 = 2 + 12
14 = 14
